As with any password scheme , however , the more people who know the password , the higher the probability that an unauthorized user will misuse it . The SSID can be changed periodically , but each user must be notified of the new ID and must reconfigure his or her wireless NIC .Additionally , most access points are set by default to broadcast the SSID in the clear , even when Wired Equivalent Privacy (WEP ) is enabled . This makes the wireless network easy to find . Your...

It is becoming very common network layout used today which connects point-to-point to a single central location . Other layouts such as BUS , RING , TREE and Mesh can also be used but can become venerable compared to STAR topology . However , STAR needs more cables compared to BUS but is very reliable for example , if one cable is cut only single pc is affected . Other advantages with STAR topology are that it is easy to install both cable and wireless and the...

They are connected by the use of a wireless media in a fashion of peer-to-peer . In an Independent Basis Service Set topology , there is a direct communication between the mobile stations . There is a limitation in the communication between a mobile station to the each and other mobile stations because of the limitations in range . Relay functions are not present in an IBSS topology , so all the mobile stations that are connected should be within the range to be able...

Wireless network which is not recognized . The nature of a Wireless network opens the door for attackers and intruders who may come from every direction . The Traffic of Wireless travels in radio waves which make it can not be restricted by the building walls . Many people do feel it comfortable to work on their laptops from any place , hackers and intruders can gain access to the network from anywhere , and it can be across the street or even from the...

The two most frequently cited reasons for slow adoption by commercial customers have been security and management . Both these issues have been addressed , with new security standards and the introduction of wireless LAN switches . While 802 .11i , the new privacy standard that incorporates the Advanced Encryption Standard (AES ) was the big story for 2004 , its adoption will be slow . Encryption is done in hardware , so implementing 802 .11i will require significant equipment upgrades . Many enterprise-grade access points that shipped during...

Internet . This projection of wireless space also allows for the sharing of connectivity with others . This would otherwise be limited through the physical connection of cables and wires . However , exposing wireless signals without encrypting them can lead to others tapping into Internet signals without prior authorization . However , the possibilities that can arise from an authorized sharing option are important . Such an option would arise from the acknowledgment and consent of both the provider and consumer in making the wireless signal...

Jackson 2001 , p110 . Architecture The architecture of the wireless LAN technology has several definitive terms such as the Station , the Basic Service Set , the Extended Service Set , and the Distribution System . Stations All of the components that literally connect unto the medium of wireless communications within the network are referred to as the station . These stations are equipped with a card known as the WNICs or the wireless network interface card . The stations are also categorized into two categories : the...

Komu Nordstrom , 1999 . Accessibility is another major feature of WLANs that make them easy to attack . Wireless LANs are very easy to access because they need to announce their existence so that existing and potential clients can connect directly to them . This is possible through a special feature known as beacons . These beacons have no privacy functions . The only security methods that can be implemented at this level are encryption and strong accesses control (Johnson , 2002 . Rogue access points can...

Besides that in the coming years mobile phones will be having Wi-Fi connections along with Bluetooth and other associated applications (Price , 2006 . Bluetooth would be replaced by Wi-Fi because its acceptance is increasing and people are shifting towards this technology because of its price and quality . Wireless MAN It 's a type of wireless network which is known as wireless Metropolitan network . In this type several wireless LAN 's can be connected together and a proper network can be created...

Over the years , it has been discovered that certain network protocols are insecure . These insecure network protocol include : standard TCP /IP and fax /modem protocols . These insecure network protocols are associated with high data overheads . Toward this end , Ryder (2001 , p .2 ) recommends the use of tamper proof methods where the information being exchanged cannot easily be interfered with . The recommended wireless standards include : Bluetooth and 801 .11 . These wireless standards have evolved in response to the need for added...

PAN . Bluetooth allows you to connect and exchange information between devices like personal digital assistants (PDAs , mobile phones , laptops , computers , printers and digital cameras via a secure , low cost , the globally available radio frequency short range . Bluetooth enables these devices to communicate among them when they come in range , even if they are not in the same room , as long as they are up to 100 meters (328 feet ) on the other , depending on the class power product . Products are...
